DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the detailed description of the preferred embodiments, it should be noted that like elements are indicated by the same reference numerals throughout the disclosure.

Firstly, please refer to FIG. 1 and FIGS. 2-A and 2-B; the present invention is related to the structure of the armrest of the back-seat of the heavy-duty motorcycle; the armrest structure is composed of one piece of arc-shaped fix-base 1, two pieces of linking-sleeve 2 and two pieces of handle 3. Fix-base 1 is arc-shaped and one rectangular-and-hollow adjusting trough 11 is respectively set at each side of the arc-shaped fix-base to cooperate with bolts 4A originally assembled around cover 4 of the oil box of the motorcycle body to fix and position components after slipping through; a penetrating-hole 12 is respectively set at the outmost end of both sides to be slipped through by bolt 1A for bolt 1A's integrating with the bottom of linking-sleeve 2 after slipping through. Moreover, linking-sleeve 2 is made to two stages with different diameters; one handle 3 integrated with one linking-sleeve 2 and respectively set at both sides of fix-base 1 has one on-slipping hole at one end; moreover, one open-cutting trough 32 and a bolting-hole are set around the on-slipping hole 31.

Assemble linking-sleeve 2 on penetrating-hole 12 of fix-base 1 with bolt 1A; then, assemble and position fix-base 1 on the position of bolts 4A around cover 4 of the oil box of the motorcycle body. Furthermore, slip handle 3 on the upper end of linking-sleeve 2 via on-slipping hole 31; then, bolt 3A is bolted into the threaded hole, and the contact force is fortified by open-cutting trough 32 around on-slipping hole 31 to position and closely combine linking-sleeve 2 with handle 3 as an integrated unit (as shown in FIG. 2-B).

The present invention provide an armrest that back-seat rider B can lay his hands on handles 3 (as shown in FIG. 3) without affecting front-seat rider A's operating the motorcycle.
